Frequently asked questions
What does 100% brightness mean?
100% maintains the original brightness. The lower values obscure the image and the higher values clarify it.

You can select values between 0% and 200% brightness.
Can I process several images?
Yes. The same level of brightness applies to all and the results are downloaded together in a ZIP file.
Are my images uploaded to a server?
No. The processing is done directly in your browser.
